Your credit score is going to impact the rate you pay. Why not work on increasing your credit score prior to buying. FHA will only require 3.5% down payment. We have excellent lenders on our website that can help you-see Resource Center/Local Businesses.
Please contact a mortgage professional (such as myself) and do not give much weight to a real estate agent answering a "financing" question. There is no need to "lease to own" if you can buy!
We have the ability to go down to a 580 score with reasonable rates.
Please call me if you would like to discuss further.
Next, even though your credit score may not support purchasing a home today - it's always wise to take the time to educate yourself on the steps needed in raising your score and setting a time frame in purchasing a home. Meeting with a loan officer now and establishing a working relationship toward your goal is advisable.
Best wishes in your plans to purchase!
